ADUM1410ARWZ-RL7 概要
Digital isolators are components that transfer digital signals across an isolation barrier without a direct electrical connection, using capacitive, inductive, or optical coupling. They are essential in systems where galvanic isolation is required for safety, noise immunity, or ground potential differences. The ADUM1410 uses iCoupler technology, which employs monolithic air-core transformers and high-speed CMOS, offering advantages over optocouplers such as higher data rates, lower power consumption, and better reliability.
Key features of the ADUM1410ARWZ-RL7 include four independent isolation channels, a maximum data rate of 1Mbps, and a CMTI of 25kV/µs, ensuring reliable operation in noisy industrial environments. The device supports a wide supply range and features a default output state of high when the input power is not applied, which is critical for fail-safe designs. The package is a 16-lead SOIC-W, which is industry-standard and easy to integrate.
Technically, the ADUM1410 uses a refresh mechanism to maintain output states during DC input, and it provides a propagation delay of approximately 100ns. The device is designed to meet UL 1577, IEC 60747-5-2, and CSA standards, ensuring compliance with international safety regulations. The isolation barrier provides reinforced insulation, making it suitable for applications requiring high isolation ratings.
Typical applications include industrial fieldbus communication, motor control, power inverters, and isolated SPI/UART interfaces. The device is also used in medical equipment, where patient safety requires galvanic isolation. Its high CMTI and low propagation delay make it ideal for high-speed data acquisition systems.
When designing with the ADUM1410, ensure proper PCB layout with adequate creepage and clearance distances for the isolation barrier. Place bypass capacitors close to the VDD pins, and consider the output load capacitance to maintain signal integrity. The device does not require external components for isolation, simplifying design.

設計ノート
For the ADUM1410ARWZ-RL7, ensure proper PCB layout with adequate creepage and clearance distances for the isolation barrier. The 16-SOIC package requires a minimum creepage of 8mm for 3750Vrms isolation. Place bypass capacitors (0.1µF) close to VDD1 and VDD2 pins to decouple high-frequency noise. Use a solid ground plane under the device to minimize EMI.
The ADUM1410ARWZ-RL7 requires a supply voltage between 2.7V and 5.5V on both VDD1 and VDD2. Ensure that the input and output sides have separate power supplies if isolation is required. The device consumes approximately 1.8mA per channel at 1Mbps, so calculate total power dissipation accordingly. Use low-ESR capacitors for stable operation.
A common mistake is to exceed the maximum data rate of 1Mbps. The ADUM1410ARWZ-RL7 is not designed for high-speed communication; for higher speeds, use the ADUM141E series. Also, ensure that the default output state (high) is acceptable for your application. If a low default is required, consider the ADUM1411 or ADUM1412 variants.
